Front camera replacement broke Siri microphone
I replaced the front camera assembly in my iPhone 6, and now I can't use Siri unless I've got headphones on, so I'm figuring the front microphone is not functioning. I bought the replacement camera for pretty cheap on Amazon: is it likely that the problem is simply a defective part? Or is there something I could have done wrong during installation that could cause this? (The front camera and proximity sensor are working fine, only problem is with the mic.)
I'm nervous about the second option because this was part of a major repair: I replaced the front panel, battery, *and* front and back cameras. (Have you ever set a drink on the roof of your car and driven off with it still there? Well, I did that with my iPhone 6 and it was lying in the middle of an intersection getting run over for an hour. Whoops.) And, aside from the front microphone and TouchID (which I know only Apple can fix), everything seems to be working fine now. So I want to know if I should just order another camera assembly (defective part), or if I actually need to take it to a professional repair shop (installation error).
Is this a good question?
